Neptune, I am planting 100 seeds of San Pedro, Bridgesii and LWs. You said you do them all in one pot, how big is or should be the pot for a 100 seeds of each of the aforementioned cacti? Can I use the sane substrate for all 3 types as my seedlings?

Thank you!

I use coarse pumice mostly for all my seedlings, you can also use coarse quarz without a problem.

You can treat them the same way and after a year when you repot, you can ad 1/5 of soil to 4/5 of minerals to the Trichocereus (San Pedro & Bridgesii).


I recommend 80% minerals and 20% crushed clay pots and charcoal for Lophis.


A pot with 4 to 5 cm edge lenght is enough for 100 seeds. No matter what cacti.

Hey Neptune, I'm about to start some t.pachanoi X SS02. Planning on using the takeaway tek to germinate seeds. Soil mix I will be using is commercial cactus soil screened of all sticks and debris to which I plan to add perlite and exo Terra riverbed sand. Should the sand be mixed in will the soil perlite or sand layer on top? Does my substrate sound OK? Very grateful for any advice you could give to a cacti noob like me.

I've been not really online the past two months but finally have the time to share what happend with you.


Ok so it's been 4 1/2 months since I sowed the seeds. The San Pedro seeds have a mad quality and nearly all the seeds that germinated are still alive, so I have hundrets of seedlings looking really great.


I will keep them in this pot for at least two more months before I'll start to separate them.

The ariocarpus seedlings are also doing great. They are compact and stay theire ground, the first tubercules are visiable on all the variations.


Ariocarpus Agavoides4 1/2 months old



Ariocarpus Bravoanus var. Hintoni 4 1/2 months




Ariocarpus Retusus var. Scapharostroides 4 1/2 months




Ariocarpus Trigonus 4 1/2 months




Ariocarpus Fissuratus 4 1/2 months





How I cared for them:


After sowing, I misted the small, heated greenhouse twice a day with water for 4 weeks.

4 weeks after sowing I've put them into a bowl with water and let the pots soak up completely.

The next 8 weeks I've misted once a day, all two days.

3 months after sowing and two since the last soaking, I've soaked the pots again in water.

The next 4 weeks I've misted only the cover of the greenhouse, but not the cacti themself.


My plann is to soak the pots up with water all two months for the next 2-3 years.

I don't mist them anymore but I keep the greenhouse cover humid.


That's all the magic.

Has it been 3 months already since my last update? I am sorry for my neglect this year, but I return with some cacti porn in case you've wondered what's happening over here in the swiss alps, where I try to play god by simulating mexican and south american climates.


First of all, check out my new topic where I show you how I repot fragile seedlings like Ariocarpus. [Click me hard!


Yes so that's what happend with my sowing from 31th january. Here are some more pictures of the repotted San Pedros and Ariocarpus. After 7 months, I managed to repot 363 San Pedro seedlings. I gave away 280 of them to friends.


San Pedro seedlings, 7 months old.

San Pedro seedlings, 7 months old already hardening them by keeping them outside of the greenhouse at lower humidty and only watering twice a month.




Ariocarpus seedlings


IMG_0732.JPG IMG_0733.JPG IMG_0837.JPG



And here are the pictures from my new sowings including many peyotes from different locations, ariocarpus, aztekium, astropyhtum and some ferocactus and other things...


100 Lophophora Williamsi KM141 that I sowed



Lophophora Alberto-Vojtechi

2X Lophophora Diffuca var, Frici

And the rest are Lophophora Williamsii from different locations


IMG_0735.JPG IMG_0736.JPG IMG_0737.JPG IMG_0738.JPG


More seedlings including some funky stuff like Ariocarpus Confusus, Astrophytum Caput-Medusae and Ferocactus Wisliszeni but also other Astrophytum's and some Turbinicarpus and even more Ferocactus, like Ferocactus Glaucescenc (THE best cactus to graft on). AND of course some Aztekium, in this case, Ritteri.

I will return


Blessings and love to all

wow  !  amazing   post what's  new with  your babies ?


So far my brown thumb  has  killed all  seedlings  I germinated  and most  baby seedlings  I have traded  for . 


I  have better luck  with  one or two yr old seedlings  and up .



My  best results is  with 10"  to 2ft  cuttings .


My avatar is my latest   cutting a  12" LumberJack T. Bridgesii .

Superb results Neptune. To even get Aztekium Ritteri to sprout is itself an accomplishment, and to have them and the Ariocarpus doing so well 7 months later is a testament to your mastery. Do you have plans to graft any of the Aztekium? If so I am pulling up a chair to watch.

I can't wait for your next update !

I have had no good luck with the aztekium seeds, I went away for two weeks and forgot to pull the plug for the heated greenhouse. When I came back I saw that all aztekium and many astorphytums rotted away!

But on the good side, I sowed more seeds, all of them turbinicarpus and geohintonia and they are doing great! I will post pics soon!

I just realised that I lost more than 200 seedlings actually because of my little mistake.


This is what happend: I keep my seedlings in small heated greenhouses by a south-fancing window.

The humidity is nearly 100% for 18 hours a day. In this time I lift off the cover twice for fresh air exchange.

At nights I plug it off and keep the ventilation slot's open so that the humidity is 55-75%.

Especially the change from 28-30°C to below 20° is important for the germination of the seeds.


I keep it like this and after 2-3 months when germination is over, I put them into a non heated greenhouse by the window.


So...I went away for 2 weeks and I forgot to pull the plug, but didn't realize that.

When I came back I saw that I lost nearly all my Astrophytum seedlings except for the A. Caput-Medusae.

I lost all my Ferocactus seedlings and all Aztekium seedlings which is very bitter!




All the surviving seedlings are in the non heated greenhouse. And I made a new sowing in august and september.


The seedlings that survived:


Lophophora (About one third of what survived)

IMG_0947.JPG IMG_0948.JPG IMG_0949.JPG


New sowing:


Geohintonia Mexicana (Very proud of this because the seedlings look fantastic and a great germ rate (80+%)






T. Polaskii




T. Saueri (3 different field numbers)


IMG_0965.JPG IMG_0966.JPG IMG_0967.JPG

T. Schmiedickeanus var. Klinkerianus








T. Pseudomacrochele




T. Swobodae




T. Lauii






The next sowing will be in january.


Peace and love to all

Namaste and thank you too all who join me on this.


It has been a year and a month since I've started this journal and I will document the cacti soon after winter dormancy.

But I can show you what happend in a year since I sowed the San Pedro Seeds on 31th january 2016.

And this last one is an Astrophytum Caput-Medusa that I've grafted on a Ferocactus in autumn 2015.


S U C C  E S S, that's the way you spell success
